ISAAC J. HARTFELD, OF ROCHESTER, NEW YORK, ASSIGNOR TO J. Y. MGCLINTOCK,OF

ROCHESTER, NEW YORK.

PROCESS AND APPARATUS FOR LAYING PAVEMENTS.

Application filed February 27, 1914, Serial No. 821,512.

To all whom it may concern:

Be it known that I, ISAAC J. HARTFELD, a citizen of the United States,residing at .w Rochester, in the county of Monroe and- 10 a new andimproved form of apparatus with which to lay pavement-s made up withblocks of uniform size.

Another object of this invention is to provide a new and improvedprocess by which 5 pavements may be laid with blocks of uniform size.

These and other objects of the invention will be fully illustrated inthe drawings, described in the specification and pointed out in theclaims at the end thereof.

In the accompanying drawings, Figure 1 is a perspective view of myimproved pallet or tray. Fig. 2 is a sectional view of the tray, sectionbeing taken on the line 2 2 of Fig. 1. Fig. 3 is'a detail view of therake. Figs. 4 and5 are plan views of the road that may be'laid by theuse of the pallet. Fig. 6 is a view of the road with the pallet in theact of laying. Fig. 7 is a plan view ofthe right hand pallet. Fig. 8 isa plan view of the left hand pallet.

This invention has for its purpose more especially the laying ofpavements or roads such as is described in the patent to J. Y.McClintock, No. 957,985, and has for its object the facilitating andcheapening of the laying of the road made up of small blocks of uniformsize. To this end, the pallet has a floor 1, on one side of which is aflange 2 which runs the full length thereof. Below the pallet are shoes3 which are preferably made of metal having the upturned end at in whichis provided the hand hole 5. These shoes rest on the ground. They arepreferably tapered so as to give the pallet a slight forwardinclination. In connection with this pallet I also provide a rake 6having a handle 7, having end members 8 and 9 fastened directly to thecross bar 10 and indirectly through the braces 11 and 12. A second crossbar 13 is also used for the purpose of strengthening it.

The use of my invention may be described as follows: After the road bedis prepared, the blocks or cubes which are preferably of Specificationof Letters Patent.

Renewed August 9, 1916. Serial No. 114,063.

about two or two and a quarter inches each way, are dumped along theside of the road. If the road is sixteen feet in width, these palletswill be preferably made each five feet, four inches long so that threeof them placed end to end will equal the width of the road. Each ofthese pallets will be operated by two men who will carry it first to apile of cubes and will put it on the ground or on a suitable stand andwill then lay preferably four rows of cubes on the pallet each row ofcubes extending the whole length of the pallet. In other words when thepallet is loaded, there will be on the pallet, four parallel rows ofcubes, five feet four inches long. The operators will then carry thepallet to the road and place the forward edge of the pallet on theblocks that have already been laid in the road. A third operator, placedon the road that has already been laid, is provided with a rake shown inFig. 3 and he will place the cross bar 10 of the rake on top of theflange 2 of the pallet taking hold of the row of cubes farthest from himand hold the cubes, drawing them against the cubes that have alreadybeen laid in the road. The two operators of the pallet will then drawthe pallet out from under the cubes, permitting the cubes to drop intothe road in place. The operators will then carry their pallet to a pileof cubes and fill it again and repeat this operation, three palletsserving to lay a section of the road the full width of the road andfour. rows long, the cubes or blocks being raked from each pallet by therake shown in Fig. 3.

It will be understood that the number of.

' pallets used may be five or six or even more and a single rake such asshown in Fig. 3 maybe used for all of said pallets, one 0peratorwith therake being capable of drawing the cubes off of the pallets as fast asfive or'six or even ten pairs of men can handle the pallets.

As above described, the apparatus will be used in laying the blocks orcubes where the rows run at right angles to the center lines of theroad. It is in many cases necessary or even desirable to lay the blocksin rows that run diagonal to the center line of the road and for thispurpose special pallets would be provided for laying the outer border ofthehighway. For this purpose a right and left hand pallet must beprovided Patented Sept. 19, 1916.

and one end of the pallet must be cut off on an exact miter, the otherend of the pallet being left square. The square end of the pallet willalways be placed toward the center of the road in laying the cubes. Themitered end will be laid to the edge or shoulder of the road and themiter must lie parallel to the middle line of the road. The right handpallet will be used for laying the outer course of blocks on the righthand side of the road. The left hand pallet will be used for laying theouter course of blocks on the left hand side of the road, while thepallets such as shown in Fig. 1 will be used for laying the intermediatecourses of blocks.

As shown in Fig. 5, the blocks are laid in rows which are at angles of30 and to the middle line of the road. The ends of the pallets used forlaying these blocks would be out at an angle of 30 to correspond and thepallets cut with such angles are shown in Figs. 7 and 8.

It will be understood that the angle might be 45 instead or any otherone that might be desired and the pallets would be cut to correspond.

I claim:

1. A paving tool comprising a pallet adapted to support horizontal rowsof small paving blocks of substantially uniform size, said pallet havinga flange extending upwardly along one side thereof, and means adapted toextend longitudinally along the flanged side of the pallet and tooperate over the pallet transversely for removing the assembled blockswithout substantial derangement of their formation.

2. A paving tool, comprising a pallet adapted to support horizontal rowsof small paving blocks of substantially uniform size, said pallet havinga flange extending upwardly along one side thereof and said pallethaving inclined shoes on its bottom, and means adapted to extendlongitudinally along the flanged side of the pallet and to operate overthe pallet transversely for re moving the assembled blocks withoutsubstantial derangement of their formation.

3. A paving tool comprising a pallet adapted to support horizontal rowsof small paving blocks of substantially uniform size,

said pallet having a flange extending upwardly along one side thereof,and a rake operable over the pallet having a flange to rest on theflange thereof and to engage with the blocks which project beyond theflange of the pallet.

4. A paving tool comprising a pallet adapted to support horizontal rowsof small paving blocks of substantially uniform size, said pallet havinga flange extending upwardly along one side thereof, and said pallethaving one of its ends mitered and adapted to be arranged substantiallyparallel to v the middle line of the roadway, and means adapted toextend longitudinally along the flanged side of the pallet and tooperate over the pallet transversely for removing the assembled blockswithout substantial derangement of their formation.

5. A paving tool, comprising a pallet adapted to support horizontal rowsof small paving blocks of substantially uniform size, said pallet havinga flange extending upwardly along one side and having one of its endssquare and the other end mitered and adapted to be arrangedsubstantially parallel to the middle line of the roadway, and meansadapted to extend longitudinally along the flanged side of the palletand to operate over the pallet transversely for removing the assembledblocks without substantial derangement of their formation.

6. The process herein described of laying a pavement, which consists infirst prepar ing a suitable foundation, arranging small cubical pavingblocks of substantially uniform size in rows upon pallets, placing saidpallets in position on the road and raking the rows of blocks from saidpallets by holding the blocks against movement and withdrawing thepallets thereby permitting the blocks to drop into place in the roadwithout substantially disturbing their arrangement.

In testimony whereof I affix my signature in presence of two witnesses.

ISAAC J. HARTFELD.
